If we remove everything that relate to elasticsearch, the same problem occurs, the schema won't update.The only way we found was to put back hibernate-search 5.7.0.Final. I don't know why thought.

I think this might be related but if we just execute a main with just the above code, there seems to be 8 "Hibernate-search: elasticsearch transport thread [number]" hanging and program won't close.I'm wondering if hibernate is waiting for those threads and won't call directly mysql.Same thing when we run it in Tomcat. After closing the server, it will run indefinitely until tomcat pop the message "server didn't stop in time, do you want to wait or kill process...".

If we enable hibernate sql log. We can clearly see the create table and every alter table. But nothing on the database is modified.

- Thanks, and let me know if i'm not at the good place to post this.

EDIT: After debugging hibernate code, we noticed that there was a quiet error while hibernate was trying to create a myIsam table. Changing code worked :

Hi,I meant that hibernate ORM didn't create schema on MySQL.Like I said in my last post, we had to switch to Mysql5InnoDB dialect for it to create it again.Everything seems to work on ellastic search schema.I updated to beta2 since then. The 8 hanging thread still happens.
